Overview

The node "Psychology AI - DeepSeek" integrates with the DeepSeek AI API to provide advanced psychology-related text processing capabilities. It supports three main operations:

  • Chat Completion: Generate text completions based on user prompts using specialized psychology AI models.
  • Content Analysis: Analyze psychology-related content to extract insights such as quality assessment, sentiment, readability, topics, or a comprehensive analysis combining these aspects.
  • Content Generation: Create multiple engaging content formats from source psychology content, such as quick facts, lifehacks, simplified science explanations, practical advice, and motivational messages.

This node is beneficial for psychologists, educators, content creators, and marketers who want to automate the generation or analysis of psychology-focused textual content. For example, it can be used to generate social media posts summarizing complex psychological concepts, analyze articles for emotional tone and scientific accuracy, or create actionable advice snippets from research papers.

Properties

Name Meaning
Operation The action to perform: "Chat Completion" (generate text from prompt), "Content Analysis" (analyze psychology content), or "Content Generation" (create multiple content formats).
Model The AI model to use: "DeepSeek Chat" (general chat model) or "DeepSeek Coder" (specialized coder model).
Prompt (For Chat Completion) The input prompt text to send to the AI for generating a completion.
Content to Analyze (For Content Analysis and Content Generation) The psychology-related text content to analyze or generate new content from.
Analysis Type (For Content Analysis) The type of analysis to perform: Quality Assessment, Sentiment Analysis, Readability Analysis, Topic Extraction, or Comprehensive Analysis.
Generation Formats (For Content Generation) The desired output content formats to generate, chosen from Quick Fact, Lifehack, Science Simplified, Practical Advice, and Motivation. Multiple formats can be selected simultaneously.
Advanced Options Collection of optional parameters controlling AI behavior and request settings:
• Temperature: randomness level (0 deterministic to 2 very random)
• Max Tokens: max tokens to generate
• Timeout: request timeout in seconds
• Max Retries: retry attempts
• System Message: system-level instruction to guide AI behavior
Additional Output Collection of options affecting output details:
• Include Usage Statistics: whether to include token usage and cost info
• Include Response Metadata: whether to include full API response metadata
• Validate JSON Response: whether to parse and validate JSON responses automatically

Output

The node outputs an array of items where each item contains a json field with the AI-generated or analyzed data structured as follows depending on the operation:

  • Chat Completion: The generated text completion string.
  • Content Analysis: A structured JSON object containing analysis results according to the selected analysis type. Examples include scores, emotional tone, readability metrics, extracted topics, and recommendations.
  • Content Generation: A JSON object with keys corresponding to the requested content formats (e.g., "quickFact", "lifehack") and values containing the generated text for each format.

If enabled, additional fields may include token usage statistics, cost information, and full API response metadata.

The node does not output binary data.

Dependencies

  • Requires an active connection to the DeepSeek AI API via an API key credential configured in n8n.
  • Network access to the DeepSeek API endpoint /chat/completions.
  • No other external dependencies are required.

Troubleshooting

  • Common Issues:

    • Invalid or missing API credentials will cause authentication failures.
    • Exceeding token limits or timeouts may result in incomplete or failed requests.
    • Improperly formatted input content or prompts may lead to unexpected or empty responses.
    • Selecting unsupported operations or models will throw errors.

  • Error Messages:

    • "Unknown operation: ..." indicates an invalid operation parameter; verify the selected operation.
    • API request failures due to network issues or rate limits may occur; increasing timeout or retry count can help.
    • JSON parsing errors if the AI response is malformed; disabling automatic JSON validation or adjusting prompts may resolve this.

  • Resolution Tips:

    • Ensure API credentials are correctly set up and valid.
    • Adjust advanced options like temperature, max tokens, timeout, and retries to optimize performance.
    • Validate input content for correctness and relevance.
    • Use the system message option to better guide AI behavior and improve response quality.
